What is the most common palpable breast mass?

• A. Lipoma
• B. Mammary duct ectasia
• C. Fibroadenoma
• D. Cyst

Answer: (D)

The most common palpable breast mass is a cyst, reflecting fibrocystic changes driven by hormonal fluctuations that dilate ducts and form fluid-filled sacs. In many adult women, these cysts are palpable as smooth, round, mobile lumps and can be tender, especially around menses. On ultrasound, a simple cyst looks anechoic with a thin wall and shows posterior acoustic enhancement, indicating fluid content. If a cyst is complex (has internal echoes, septations, or thick walls), it requires closer evaluation to exclude something more concerning. Fibroadenoma is a very common solid mass in younger women and often presents as a discrete, mobile lump, but it’s generally more prevalent in younger populations, whereas cysts are the more frequent palpable mass across a broader age range. Lipomas are less common, and mammary duct ectasia typically presents with nipple discharge or ductal changes rather than a discrete palpable mass.
